RAT CHET-WREN CH.

'l'o all whom "it may concern:

Be it known that I, SAMUEL P. PERUSSINA, a citizen of the United States,residing at Galveston, in the county of Galveston and State of Texas,have invented certain new and useful Improvements in Ratchet- Wrenches,of which the following is a specilication.

My invention relates to an improvement in ratchet wrenches, and theobject is to provide a wrench in which the rotating heads or sockets canbe removed, and heads of different bores substituted.

Another object is to provide means whereby the heads or sockets arecapable of rotation either to the right or left at the wish of theoperator.

My invention relates to certain other novel features of construction andcombinations of parts which will be hereinafter described and pointedout in the claim.

In the accompanying drawings :-Figure l is a plan view. Fig. 9. is a topview with the cover removed. Fig. 3 is a sectional view on the line rcwof Fig. 1. Fig. 4 is a view of the locking means. Fig. 5 is a view ofthe head or socket. Fig. 6 is a view in side elevation of the head orsocket, and Fig. 7 is a detail segmental view showing the manner ofconnecting the cover to the base.

A, represents the wrench, and B the base, which is cut away along itsupper edge, as at 2, and pawls 3, 3, are pivotally mounted thereon, andheld by pins 1, 4t. At the front end a recess 5 is formed and in thebase of the recess an aperture 7 is formed, in which the head or socketC is received. The head has -a bore 6 which engages the nut, bolthead orthe like, and the bore can be made of any desired form. The ratchetteeth 8 projecting outwardly from the rim of the head or socket G areadapted to be received in the recess 5, and the wall of the recess isprovided with openings 9, 9, for the ends 10, 10, of the pawls 3, toengage the teeth 8 of the head C. The opposite ends of the pawls areprovided with rounded knobs 11, and springs 12 secured to the body ofthe wrench en- Specification of Letters Patent. Application filedFebruary 17', 1906.

Patented Mar. 1, 1910. Serial No. 301,712.

gaging the pawls tend to throw them outward and in engagement with theteeth 8 of the head or socket.

A look or key 13 of the wrench and is held in position by a screw 14.Projecting outwardly from the lock, arms 15 are formed, which areprovided with projections 16, 16, adapted to engage the knobs 11 of thepawls 3.

A cover 17 sliding in grooves 18, passes over the various parts, and hasan elongated slot 19 which fits around the lock 13. Between the coverand base B of the wrench is a plate 20, which has an opening 21 whichsurrounds the head 0 and prevents any lateral play.

Extending around the edge of the wrench a metal band 22 is secured.

The operation of the wrench is as follows z-The bore of the head C isplaced around the nut to be screwed up or removed, and the lock 13 isturned so that the projection 16 will pass over the knob 11 and hold thepawl 3 out of engagement with the teeth 8 of the head C, while the pawlwhich is free will be in engagement with the teeth 8, and by rotatingthe handle 23 of the wrench, backward and forward the nut will be causedto move on the bolt. For instance, as shown in Fig. 2, as the wrench isrotated to the left the head remains stationary, but when rotated to theright it is revolved and at the same time carries the nut with it.

Of course, when both pawls are free, or the lock 13 is not in engagementwith either of them, both pawls engage the teeth 8, by the springs 12throwing them outward.

It will be seen that a head or socket having a different sized bore canbe easily placed in the wrench by simply withdrawing the cover, andremoving the plate 20.

It is evident that many slight changes might be made in the form andarrangement of the several parts described, without departing from thespirit and scope of my invention and hence I do not wish to limit myselfto the exact construction herein set forth.

Having fully described my invention,

passes through the body out of engagement With the teeth a plate havingan opening therein through Which the head is received whereby the headis held in position, said plate extending over 10 the pavvls forretaining them in position, and a cover slidably mounted on the base forholding the plate in position.
